T (056 whmn it may concern.-

Be it known that we, JosEPE P. ScHoWAL- TER and GEORGE A. ROSENBAUER,citizens of the United States, and residents of Milwau kee, in thecounty of Milwaukee and State of Wisconsin, have invented certain newand usefullmprovements in Bicycle Handle-Bars and we do hereby declarethat the following is a full, clear, and exact description thereof. Ourinvention has for its object to simplify and cheapen the manufacture ofbicycle handle-bars having grip members adjustable to various angles andalso to utilize shank=expanders as parts of said handle-bars.

Afurther object of our invention is to overcome sticking of theshank-expa'nders.

With these objects in view our invention consists in certainpeculiarities of construction and combination of parts hereinafterparticularly set forthwith reference to the accompanying drawings andsubsequently claimed.. t

Figure l of the drawings represents an elevation of a portion of ourimproved handlebar, partly broken and in section; Figs. 2 and 3, detailsectional views respectively indicated by lines 2 2 and 3 3 in the firstfigure; Fig. 4, a detail elevation of a portion of one of the adjustablegrip members of the handlebar, and Fig. 5 a side elevation of theassembled parts of the device having a broken pivot-bolt.

' Referring by letter to the drawings, A indicates a metallic angularshell constituting ahollow head,having 9. depending stem b, to which isbrazed a tube B, herein shown as having longitudinal kerfs c atintervals cir cumferentially of its lower end. The headstem and tube inrigid union therewith con- 40 stitute the shank of our improvedhandlebar, designed for vertically-adjustable connection with thesteering-fork shank of a bicycle. Arranged to turn in the head A is arod D, and the lower end of this rod has screw-thread connection with aconical block or shell E, engaging the kerfed end of said shank toconstitute an expander for the same.

The upper end of the rod is squared to accommodate a wrench and providedwith a stop-flange cl, that rests upon the head aforesaid. Rotatorymovement of rod D operates to efiect vertical adjustment of the expanderE, with which it has screw-thread connection.

Gear-toothed rounded inner ends g h of handle-bar grip members G H arearranged on pivot-bolts I J within head Ato mesh with each other, andthe toothed faces of these grip-member extremities are peripherallygrooved to aiiord clearance for the expan deradjusting rod abovespecified. The head of each pivot-bolt is made round to lit acorresponding aperture in the head A, and the fiat inner side of thebolt-head co mes snug against the rounded toothed end of thecorrespondmg grip memberof the handle-bar. As herein shown, eachbolt-head may be provided with an inwardly-extending lug e, that engagesa socket in the adjacent grip member, and thus the latter and its pivot-bolt are in lock with each other to turn together. The toothed endof each grip member G H has that side thereof farthest from the head ofits corresponding pivot-bolt provided with a circular series of radialwedge-ribs, and this ribbed surface meshes with a similar inner surfaceon a disk K, made fast in acorresponding side aperture of thehandle-barhead, each disk being centrally apertured for the ongagementtherewith of a pivot-bolt. Washers p and clamp-nuts L engage.the aforesaid pivot-bolts outside the head of the handle bar, and byloosening the nuts slack is bad to permit disengagement of the opposingwedgerib surfaces, so that the grip members G H may be readily adj nstedto various angles, said grip members and pivot-bolts turning together insaid head. The adjustment having been effected, tightening of theloosened nuts will cause lockin g together of opposing wedgerib surfacesabove specified to maintain the grip members at the desired angle, thehandle-bar being then rigid at all points.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

A bicycle handlebar com prisin g a hollow head provided with a dependingtubular shank longitudinally kerfed at intervals circumferentially ofits lower end, an expander engaging the kerfed end of the shank, a rodthat turns in the head and has screw-thread connectionwith the expander,grip members having rounded toothed ends in pivotallyadjustableconnection with said head to mesh with each other therein, and means formaintaining pivotal adjustment of the grip members, the toothed faces ofthese grip members being grooved to afford clearance for theexpander-adjusting rod.

In testimony that we claim the foregoing Io we have hereunto set ourhands, at Milwaukee, in the county of Milwaukee and State of \Visconsin,in the presence of two witnesses.
